TERMINOLOGY

As used herein, the term “core” means any structure that is in contact with a substantial portion of the interior surface of a film roll.

As used herein, the term “coreless” means any film product which does not include a cardboard, plastic or metal core or any other core which cannot be disposed of or recycled using standard recycling procedures (e.g., because of adhesives, size, or any limitation of a recycling process which causes an added disposal or recycling cost). The term “coreless” may include a reusable, disposable or recyclable liner. “Coreless” may also include film products which use an interior structure adapted to use less material than a traditional core structure, such as rings, strips, bars and any other structure of device known in the art to form an interior structure. “Coreless” may also include any film roll which requires the use of stabilizing (e.g., retrofitting) structures on a wrapping machine to eliminate the need for a core.

As used herein, the term “film” includes flexible packaging material for any packaging use known in the art (e.g., industrial, medical, food and beverage, retail, shipping, pharmaceutical). Film may include organic and non-organic materials, biodegradable materials, carbon-based and non-carbon based materials, previously recycled materials, composite materials, laminate materials, metallic materials, cast films, blown films, metalized films, barrier films, heat treated materials, temperate materials, protective materials, light resistant materials, light sensitive materials, aerated materials, vacuum films, chemical resistant materials, chemical sensitive materials, reinforced materials, x-ray resistant materials, time-reactive materials, water and heat resistant materials, impact resistant materials, containment materials, multiple-layered materials, flattened materials, pre-stretched materials, biodegradable materials, films or other materials structurally integrated with other materials, combinations of materials and other film equivalent or film-related products known in the art.

As used herein, the term “pre-stretched” refers to a film which is stretched before being wound or provided as a product.

As used herein, the term “retrofitting stabilizing component” refers to any structure or device which may be used in conjunction with a coreless film roll in order to make the coreless film roll usable with existing wrapping machines.

Background

Film which is wound, rolled or layered for use has an array of uses for industrial, medical, food and beverage, scientific and consumer uses.

For example, in order to stabilize and protect items stacked on a pallet, whether for storage or transport, a film is wrapped around the articles and pallet. Pallets may be wrapped by a machine or by hand. When wrapped by a machine, a roll of film is placed on an arm of the machine, and a pallet on a rotating platform. As the pallet spins, film is pulled from the roll and accumulates around the pallet and products. When wrapped by hand, a user may walk around a pallet carrying a roll of film and wrap the film around the pallet and products. Usually the film has a gripping texture and some stretch which allows the plastic film to grip the articles being wrapped and secure them. Whether a pallet is wrapped by machine or by hand, an amount of tension may or may not be required to stretch the film and allow it to more securely grip the items being wrapped.

Film known in the art is provided in rolls wound around a cardboard, plastic or metal tube known as a core. Cores must be of sufficient strength to withstand the pressures caused by the high-speed winding of film around the core and the total weight of the final rolled product to prevent the roll from collapsing. Cores, therefore, are usually made from a thick (up to 2 inches or more) tube made of cardboard or other structural materials and may contain an adhesive between layers of material to provide additional stability.

One problem with existing cores is the weight. Cores can weigh up to 5 pounds or more. When shipping film rolls, a significant portion of the fee is attributable to the weight of the core and freight. The weight can also cause workplace injuries when carrying film rolls, loading film rolls to a wrapping machine or even hand wrapping pallets. Women and smaller workers may not even be able to lift film rolls because of the weight.

A second problem known in the art with traditional cores is the inability to dispose of the cores. Cardboard cores may be recyclable if there is no adhesive in the core, but most recycling companies will not take cores unless they are already flattened. In order to flatten a core, it must be run over by a forklift or other industrial machine. Getting a core into condition for recycling takes time and labor, and therefore costs companies money. In addition, if recyclable cores are thrown in the trash, some waste management companies charge a fee for disposal of green products.

Due to the added cost and labor, the presence of glue within the cores, or core material, some companies may not recycle cores, but disposal may still be an issue. If cores are not flattened, they take up significant space in waste containers and dumpsters. Large companies may go through multiple rolls of film a day, resulting in many cores to be disposed of. Dumpster costs, including the number of dumpsters and the frequency of pick-up, are also expensive. Some waste companies even charge additional fees for collecting high-volume waste.

In addition to core waste, companies also end up using more film to wrap pallets than is necessary. Film may be stretched before it is used to wrap, but wrapping machines and individuals wrapping by hand are unable to fully stretch film before it is wrapped around a pallet. As a result, more film is used than necessary. Wrapping machines also experience additional stress when stretching film for use.

In order to overcome the problem of wasted film, machines are known in the art which pre-stretch and rewind the film. By pre-stretching the rolls, less force is needed to tighten wrap around a pallet and less wrap is used. Pre-stretching the film also helps lower the weight of the rolls. Pre-stretched film, however, is only used in the art to hand wrap pallets.

Technology exists in the art to make coreless film products; however coreless film cannot be used on existing wrapping machines. For example, NO.EL, a company operating out of Italy, manufactures and sells a machine capable of winding coreless film rolls. While the resulting rolls may be coreless, they cannot be used on current wrapping machines because the rolls will not be secured or stable on the machine arm. As a result, rolls unwind from the inside out and become tangled and unusable. Wrapping machines are expensive and last a long time, and the purchase of a wrapping machine is considered a large investment for companies. Manufacturers of film rolls are therefore not offering coreless film rolls or investing in the NO.EL machine because no clients would be able to use coreless film rolls.

SUMMARY OF THE INVENTION

The present invention is a coreless pre-stretched film roll product which may be used with both hand wrapping devices and wrapping machines with or without stabilizing components. A thin reinforcing liner is provided in the center of a film roll to prevent the interior end from unraveling. Plugs may also be used on one or both ends of a coreless film roll to stabilize the roll for transport and storage. Coreless rolls to be used in a wrapping machine also include retrofitting stabilizing components which allow the coreless rolls to be used with current wrapping machines.

The present invention decreases the weight of and disposal and freight costs associated with film rolls by removing the traditional cardboard core. Thin, disposable liners and stabilizing plugs may be used with any rolled product, including, but not limited to, paper products, plastic products, fabric products or any other material which may be rolled, in order to decrease the weight and disposal, freight and manufacturing costs associated with cored products.

It should be understood that the drawings are not necessarily to scale; instead emphasis has been placed upon illustrating the principles of the invention. In addition, in the embodiments depicted herein, like reference numerals in the various drawings refer to identical or near identical structural elements.

Moreover, the terms “substantially” or “approximately” as used herein may be applied to modify any quantitative representation that could permissibly vary without resulting in a change in the basic function to which it is related.

FIGS. 1 and 2 are exemplary embodiments of industrial stretch film dispensing apparatus 100 for use with hand-wrapping. As shown in FIGS. 1 and 2, plastic film is wound around liner 20 in order to prevent the interior end of the film from unraveling. As illustrated, liner 20 creates a uniform cylindrical channel running through the center of industrial stretch film dispensing apparatus 100, 200.

In the exemplary embodiment shown, liner 20 is a thin plastic tube around which pre-stretched plastic film is wound. In further exemplary embodiments, pre-stretched film may be wound without a central core, and liner 20 inserted after the roll has formed. In still further exemplary embodiments, liner 20 may be cardboard, laminated paper, layer of adhesive or any other material known in the art which may provide a thin central liner to prevent the interior end of the roll from unraveling. Liner 20 must also be of sufficient strength to withstand forces generated during rewinding, if film is wound directly around liner 20, and the weight of the plastic film after it is rolled.

In the exemplary embodiments shown in FIGS. 1 and 2, liner 20 is showed as physically contacting a substantial portion of the interior surface of industrial stretch film dispensing apparatus 100, 200. In further exemplary embodiments, liner 20 may be adapted to contact only a minimal amount of the interior surface of industrial stretch film dispensing apparatus 100, 200. For example, liner 20 may be a brace, bar, series of rings, layer of adhesive, any other material, structure or device which may prevent the interior end of film from unraveling and aid in stabilizing industrial stretch film dispensing apparatus 100, 200 or combinations of these materials, structures and devices.

FIG. 1 also illustrates plugs 40 which may be inserted into either end of industrial stretch film dispensing apparatus 100. In the exemplary embodiment shown, plugs 40 are small components with cylindrical protuberance 42 adapted to fit inside liner 20. Grasping portion 45 projects from cylindrical protuberance 42 to allow a user to insert or remove plugs 40. In some exemplary embodiments, grasping component 45 may be any shape or design known in the art to allow a user to easily grasp plug 40, including, but not limited to, a handle, a loop, a knob, a contour or any combination of these structures.

In further exemplary embodiments, plugs 40 may be configured to fit entirely within liner 20 so that grasping portion 45 does not protrude above the ends of roll 200.

In the exemplary embodiment shown in FIG. 1, plugs 40 are made of a plastic of sufficient strength to support roll 100 and prevent industrial stretch film dispensing apparatus 100 from collapsing. However, in further exemplary embodiments, plugs 40 may be of any material known in the art to support and reinforce industrial stretch film dispensing apparatus 100 and prevent it from collapsing.

As illustrated in FIG. 1, pre-stretching film causes edges 30 of the film to become uneven. When wrapped, uneven edges 30 may become damaged if the film is dropped or stored on its ends. Plugs 40 may be configured with a covering area which sits against edges 30 and protects them from damage.

While in the exemplary embodiments shown in FIGS. 1 and 2 plugs 40 are only shown used in conjunction with industrial stretch film dispensing apparatus 100, plugs 40 may be used with industrial stretch film dispensing apparatus 200 as well.

FIGS. 3 and 4 are exemplary embodiments of industrial stretch film dispensing apparatus 300, 400 for use with wrapping machines. Illustrated in the exemplary embodiments shown in FIGS. 3 and 4 are liners 20, which create a uniform cylindrical channel through the center of industrial stretch film dispensing apparatus 300, 400. When used with a wrapping machine, the uniform cylindrical channel receives the wrapping machine arm.

In the exemplary embodiments shown, liners 20 are thin plastic rolls which prevent the interior end of film from unraveling. Because industrial stretch film dispensing apparatus 300 and 400 are to be used in a wrapping machine, liners 20, in addition to being able to withstand the weight of the film roll, need to be sufficiently durable to withstand the forces generated when plastic wrap is quickly pulled from industrial stretch film dispensing apparatus 300, 400 and industrial stretch film dispensing apparatus 300, 400 are quickly spun around a machine arm.

In some exemplary embodiments, machine industrial stretch film dispensing apparatus 300, 400 may contain an additional liner of a material with low friction to allow industrial stretch film dispensing apparatus 300, 400 to spin easily on a machine. In still further exemplary embodiments, liners 20 for rolls 300, 400 may be weighted or contain other design modifications which help stabilize industrial stretch film dispensing apparatus 300, 400 on a machine.

Also shown in FIGS. 3 and 4 are plugs 40, which stabilize industrial stretch film dispensing apparatus 300, 400 for transport and storage. Plugs 40 are to be removed from industrial stretch film dispensing apparatus 300, 400 before use on a machine.

The exemplary industrial stretch film dispensing apparatus 300, 400 illustrated in FIGS. 3 and 4 are designed for use with wrapping machines. The uniform cylindrical channel extending the length of industrial stretch film dispensing apparatus 300, 400 receives the wrapping machine arm. Wrapping machine arms known in the art are manufactured to accommodate film rolls with central diameters of 1-2 inches with a thick and solid core. Because industrial stretch film dispensing apparatus 300, 400 does not contain a standard core known in the art, industrial stretch film dispensing apparatus 300, 400 may be manufactured with any size uniform cylindrical channel. In order to work with wrapping machines known in the art, however, the uniform cylindrical channel must be at least great enough to fit a standard wrapping machine arm of approximately 2 inches. However, industrial stretch film dispensing apparatus 300, 400 may be manufactured with central uniform cylindrical channels with diameters of 3 inches to 5 feet, and up to 10 feet.

While in the exemplary embodiments shown in FIGS. 1-4 industrial stretch film dispensing apparatus 100, 200, 300, 400 are shown including multiple layers of industrial film material, industrial stretch film dispensing apparatus 100, 200, 300, 400 may contain only a single layer of film. Without a core, industrial stretch film dispensing apparatus 100, 200, 300, 400 may completely unwind and be used entirely.

In the exemplary embodiments described in FIGS. 1-4, industrial stretch film dispensing apparatus 100, 200, 300, 400, each contain a film product which is known in the art for wrapping pallets, products or other items. In further exemplary embodiments, however, liner 20 and plugs 40 may be used with any rolled product, including, but not limited to, paper products, fabric products, plastic products, and any other material or product which may be rolled.

FIG. 5 is an exemplary embodiment of industrial stretch film dispensing apparatus 300 with retrofitting stabilizing component 50. Original cores known in the art were sometimes up to 2 inches thick and had an inner hollow diameter of approximately 1-2 inches. Wrapping machines are therefore manufactured with an arm to accommodate a film roll with a 1-2 inch diameter central hole. In the exemplary embodiments described in FIGS. 3 and 4, above, industrial stretch film dispensing apparatus 300, 400 are coreless with liner 20. As a result, the central uniform cylindrical channel may have a diameter larger than that of traditional cored rolls. If industrial stretch film dispensing apparatus 300, 400 were used on existing machines, industrial stretch film dispensing apparatus 300, 400 would not be stable.

Retrofitting stabilizing component 50 is a flexible ring which is specifically designed to fit around the arm of existing machines and compensate for the difference in internal diameters between cored machine rolls and coreless machine rolls. In the exemplary embodiment shown in FIG. 5, retrofitting stabilizing component 50 is designed to be placed inside liner 20 before industrial stretch film dispensing apparatus 300 is placed on a machine. Retrofitting stabilizing component 50 may be permanently or removably secured to liner 20. In further exemplary embodiments, retrofitting stabilizing component 50 may be designed to secure to a machine prior before a coreless machine roll is placed on the arm.

In some exemplary embodiments, retrofitting stabilizing component 50 may be disposable or reusable. In further exemplary embodiments, retrofitting stabilizing component 50 may be a structure other than a flexible ring. For example, retrofitting stabilizing component 50 may be a wedge, clamp, bar, cap, contours, spring assembly, inflatable device, reusable core or any other device or structure known in the art which may be used to securely hold a coreless roll against a machine.

In still further exemplary embodiments, retrofitting stabilizing component 50 may include a mechanized component which works to secure industrial stretch film dispensing apparatus on a machine arm. For example, retrofitting stabilizing component 50 may be a structure which exerts a force on the interior surface of a cylindrical channel of an industrial stretch film dispensing apparatus, such as a spring mechanism. The force exerted must be enough to stabilize the industrial stretch film dispensing apparatus while not damaging any of the layers of industrial film product. In still further exemplary embodiments, retrofitting stabilizing component 50 may include an expansion component, such as a compressible or inflatable material, which expands to contact the interior surface of the uniform cylindrical channel of an industrial stretch film dispensing apparatus.

Retrofitting stabilizing component 50 may be any structure or device which increases the diameter of a wrapping machine arm and comes into contact with the inner surface of the uniform cylindrical channel or liner 20 of an industrial stretch film dispensing apparatus. As illustrated in FIG. 5, retrofitting stabilizing component 50 does not affect the rotational motion of industrial stretch film dispensing apparatus. It is critical that retrofitting stabilizing component 50 only secure industrial stretch film dispensing apparatus to the machine arm and not interfere with the rotational motion of industrial stretch film dispensing apparatus so that industrial stretch film dispensing apparatus and retrofitting stabilizing component 50 may be used with any existing wrapping machine.

In still further exemplary embodiments, there may be more than one retrofitting stabilizing component 50, and retrofitting stabilizing components 50 may be of the same design or of differing designs. A single retrofitting stabilizing component 50 may also include multiple components. For example, a single retrofitting stabilizing component 50 may include multiple members which contact the inner surface of a uniform cylindrical channel.

Retrofitting stabilizing components 50 may also be used with industrial stretch film dispensing apparatus 100, 200 described above if industrial stretch film dispensing apparatus 100, 200 are used with hand wrapping devices known in the art which are designed to hold and secure rolls with traditional cores.

In some exemplary embodiments, liner 20, or the inner surface of a cylindrical channel itself, may be configured to interact with retrofitting stabilizing component 50. For example, liner 20 or cylindrical channel may include contours, surfaces, or other structures, such as a stabilizing strip, with which a retrofitting stabilizing component 50 interacts. Structures and surfaces integrally associated with a cylindrical channel may help retrofitting stabilizing component 50 secure industrial stretch film dispensing apparatus and may also protect the film product from damage by a retrofitting stabilizing component 50.

While in the exemplary embodiment shown in FIG. 5, retrofitting stabilizing component 50 is in physical contact with only a small percentage of the inner surface of the cylindrical channel, in further exemplary embodiments, a retrofitting stabilizing component 50 may be in contact with between 10 and 100% of the interior of a cylindrical channel.

FIGS. 6 a, 6 b, and 6 c illustrate alternative exemplary embodiments of retrofitting stabilizing component 50. As illustrated in FIG. 6 a, retrofitting stabilizing component 50 contains a plurality of protuberance members 68 radiating from the surface of base component 69. When industrial stretch film dispensing apparatus 600 is placed on a wrapping machine arm and over retrofitting stabilizing component 50, protuberance members 68 exert a force on the inner surface of the cylindrical channel of industrial stretch film dispensing apparatus to stabilize and secure it to machine arm 60. In some exemplary embodiments, the protuberance members may include spring mechanisms to exert the force on the inner surface of the cylindrical channel. In further exemplary embodiments, retrofitting stabilizing component 50 may be mechanized. Retrofitting stabilizing component 50 may be removable from machine arm 60.

FIG. 6 b shows an alternative exemplary embodiment of retrofitting stabilizing component 50 integrally associated with wrapping machine arm 60. As illustrated in the exemplary embodiment shown in FIG. 6 b, retrofitting stabilizing component 50 consists of a plurality compressible securing members 70 on wrapping machine arm 60. When coreless industrial stretch film dispensing apparatus 600 is placed over machine arm 60, and therefore over retrofitting stabilizing component 50, compressible securing members 70 exert a force on the inner surface of the cylindrical channel of industrial stretch film dispensing apparatus 600. Compressible securing members 70 of retrofitting stabilizing component 50 compress in order to allow industrial stretch film dispensing apparatus 600 to slide over retrofitting stabilizing component 50. Because retrofitting stabilizing component 50 compresses, a wrapping machine containing a retrofitting stabilizing component 50 as illustrated in the exemplary embodiment in FIG. 6 b may be used with current film rolls containing a traditional core.

In further exemplary embodiments, retrofitting stabilizing component 50 integrally associated with a wrapping machine arm may be any structure or device known in the art to allow an industrial stretch film dispensing apparatus to slide completely over the wrapping machine arm and exert a force on the inner surface of the cylindrical channel of industrial stretch film dispensing apparatus.

FIG. 6 c is an exemplary embodiment of retrofitting stabilizing component 50 integrally associated with liner 20 of industrial stretch film dispensing apparatus 600. In the exemplary embodiment shown, retrofitting stabilizing component 50 consists of a plurality of gripping structures 72 manufactured on the outer surface of liner 20. When industrial stretch film dispensing apparatus 600 is placed over machine arm 60, gripping structures 72 engage the surface of machine arm 60 to secure and stabilizing industrial stretch film dispensing apparatus 600. In the exemplary embodiment shown, gripping members 72 are contours which increase the friction between the outer surface of machine arm 60 and inner surface of the cylindrical channel of industrial stretch film dispensing apparatus 600. In further exemplary embodiments, gripping members 72 may be any structure or device known in the art which may be integrally associated with liner 20 and help secure industrial stretch film dispensing apparatus 600 to a wrapping machine arm 60, including, but not limited to, adhesives, compressible materials, mechanized devices, spring assemblies, contours, friction-increasing textures, and combinations of these structures and devices.

While in the exemplary embodiments illustrated in FIGS. 5-6 c retrofitting stabilizing components 50 are of a single design, in further exemplary embodiments, retrofitting stabilizing components 50 may utilize multiple structures or devices to secure industrial stretch film dispensing apparatus to machine arm 60. In still further exemplary embodiments, retrofitting stabilizing components 50 may use combinations of structures or devices which may be removable from machine arm 60 or cylindrical channel and structures or devices which may be integrally associated with machine arm 60 or cylindrical channel.
